Sorry Greg,
Didn't mean it quite that way. Debian "pure AMD64" is now a fully 64
bit OS: there are 32 bit legacy/compatibility libraries available to
link against if you really feel you must :) But it's 64 bit - in exactly
the same way that Alpha always was.
If you happen to be running 32 bit machines on the desktop, you can
still install exactly the same apps. as are available in the 64 bit
version. Thus, Debian's the same even across architectures.
A case in point: one year I took an Alpha running Debian to the Debian
stand at LinuxWorld in London: the next year I took a Sun Sparc 20 dual
processor machine. Both ran exactly the same apps. as the Intel
architecture machines next to them - and had virtually identical install
routines.
I'm talking at my local LUG tomorrow night about the NSLU2.
(Tiny Intel/Marvell Xscale machine with 8MB flash and 32MB RAM, 2 x USB
2.0 and 10/100 Ethernet port)
For grins, I installed Debian on it yesterday. It has Apache, print
capability, X.org and Iceweasel, the Debian Firefox equivalent. It also
has the usual development tools, gcc etc. etc. as native ARM packages.
The only difference in the install (apart from speed): I had to arrange
to re-flash the flash memory and the initial login was via ssh. I'm not
sure whether ATLAS and MPICH would do well - but I'm fairly sure they're
available for it. Floating point is abyssmal because of emulation issues
- hence a change to the new ARM EABI in due course.
